Computational Statistics in Python

Looks nice, but skimming through it I saw loads of typos. Makes you wonder how much effort was put into this.

Anybody knows a book on similar topic with lots of practical examples and exercises? By "practical" I mean that instead of mathematical definition of covariance and example of how to use it in R/Python author would provide us with some real world use case where we're trying to obtain some information about the real world, given some data. Like list of water temperature measurements over the years, number of pirates… you've got the idea.
